This research is based on cases of hail that caused flooding in Binjai City on May 22, 2022. This study aims to see the correlation and regression of the Atmospheric Stability index value on cloud top temperature data from the Himawari-8 satellite imagery. So that the ERA-5 reanalysis data can be used to obtain cloud top temperatures in predicting hail events. The indices used in this study are CAPE, KI and TTI. The data used is located in Binjai City with correlation testing from 00UTC – 24UTC on May 22, 2022. Supported data is used in the form of sea surface temperature and wind conditions and looks at the causes of hail at the research location. The method used is Spearman's rank correlation with the results obtained in the form of a correlation value at the K index of -0.651, a correlation of the TT index of -0.563, and a correlation of the CAPE index of -0.348. The simple linear regression results also show a negative gradient line. This shows that the increase in the value of the stability index is in line with the decrease in cloud top temperature. So that the stability index data can be used as a benchmark in estimating cloud top temperatures in the case of convective cloud formation which causes hail.

Barium M-hexaferite is a material which has the potential to be developed as a magnetic material which is needed in various fields of application. Various methods have been used to produce this material, but in general these methods require heating at relatively high temperatures. This research was conducted to characterize the magnetic properties and microwave absorption of barium M-hexaferrite which was synthesized using the coprecipitation method by sintering at low temperatures. Synthesis of barium M-hexaferite was carried out using BaCO3, FeCl3. 6H2O, HCl, NH4OH. The results of the coprecipitation were dried using a light bulb at a temperature of 850C, then sintered at a 3000C with variations in holding times of 1 hour, 3 hours and 5 hours. The magnetic properties of the synthesized materials were tested using VSM, while the properties of microwave absorption were characterized using VNA. From the VSM test results, it can be determined that the highest remanence magnetization and coercivity values were found in the samples sintered at 3000C for 3 hours, namely Mr 0.103 emu/gram and Hc 0.058 Tesla. Meanwhile, from testing the absorption properties of the material for microwaves using VNA, it was found that the largest reflection loss value was found in the sample which was calcined for 3 hours, which was 52.4 dB or equivalent to an absorption of 99% at a frequency of 11 GHz. From the research it was found that barium M-hexaferite as a result of coprecipitation can be developed into a good microwave absorbent material.

This research aims to analyze the environmental literacy of the community in Kampung Warna-warni Jodipan (KWJ). Environmental literacy is conducted to determine the community's ability to understand and maintain the environment to ensure its balance and prevent pollution. Knowledge and attitudes are important aspects used to measure environmental literacy. This research was conducted on KWJ community involving 83 people as research samples. Data were collected through questionnaires, interviews, and observations using Google Form. Data analysis used Guttman Scale and Likert Scale. The results of data analysis according to the Guttman Scale with a moderate score range (11-16) showed that the community's knowledge is not yet fully maximal in understanding environmental literacy, but with KWJ, the attitudes shown by the community begin to emerge to maintain and preserve their environment. The results of this research can be used as a learning resource for biology in high school class X. This research can be used as a step to improve understanding of environmental literacy.
